SO Belt grader is a high-speed and highly precise device engineered for grading round vegetables.
A grader can be equipped with a rubber or a metal grading belt. A rubber belts with square holes are recommended to grade potatoes. Rubber belts are extremely product-friendly and provide that potatoes are not going to be damaged. Metal belts with hexagonal holes are usually used for onions. They guarantee highest capacity and precision.
A set of motor-driven shakers mounted under the grading belt prevent blocking of the vegetables in the grading holes. The speed of the grading belt speed and the shakers is adjustable.
A single grading module, which is equipped with one grading belt and an unloading conveyor belt for under-size allows us to get two different sizes of vegetables. Modular construction lets us setting any number of modules and getting required number of sizes.
